This is a whole lesson looking at sampling as a whole, with the main bulk of the lesson looking at stratified sampling. An important area for anyone doing Statistics, whether at GCSE or at A-Level and has lots of cross curricular links.
It comes with lots of keys words, learning objectives, starter and plenary... it comes with a worksheet that I got from TES, but I have added ANSWERS! and some exam questions on stratified sampling, which I also had.
